The slim girl was in her first year at college, and she was a flibbertyjibbit, who totally lacked discipline. She flitted around and dabbled in her college courses, but wasn't keeping her grades up. Her money didn't last long, either. It just seemed to melt away. She couldn't help herself, and hoped an answer would appear somehow.
She and her parents were all at their wits' end, until her older sister made a suggestion. The sister, who hoped to get a nursing degree, proposed that she transfer to the younger sister's college. They would save money by living together, instead of having two apartments to pay rent on.
The older sister would be a great help to the younger girl, who obviously couldn't fend for herself. The young girl would greatly benefit from some discipline, and her sister was just the one to give it!
I'm looking for the older sister.
